^aTotal reads: the number of clean reads
^bTotal mapped: the number of clean reads that could be mapped to the chicken genome
^cMultiple mapped: the number of clean reads corresponding to a plurality of locations in the genome
^dUniquely mapped: the number of clean reads corresponding to a unique location in the genome
^eReads map to “+”: reads mapped to the sense strand
^fReads map to “−”: reads mapped to the antisense strand
